I think there's a real chance that Ash will only use Pikachu, and Go will only use Scorbunny (the other Pokemon he catches will just be sent to the lab if this is the case). Think about it
>Series is meant to be more episodic
>They have been giving Ash less Pokemon each gen
>We don't have any additional Pokemon confirmed yet, which is basically unheard of for the series
>They've established a precedent for Ash only using Pikachu with the Power of Us
